I was part of a Squadron which had a nuke strike mission. At the end of the certification process we were asked if we were willing to perform the mission. One pilot responded no. He was grounded. What did he think our job was, dropping pixie dust?
Each pilot joining a company knows what the rules are in advance. Each pilot makes a cost/benefit analysis. Some have chosen poorly. Some have had an excrement sandwich served up to them through no fault of their own.
We live in a world as it is, not as we wish it would be. At the majority of carriers, seniority is that world.
